bearings7, secured to one side of the vbaling chamber 1. Two horizontalcurvedne'edles 7, are secured at one set of ends, one above the other,to the shaft 6, said needlesbeing adapted, when-the jshaft is rocked ytoand. v fro, to pass through longitudinal slots'8" -provided in oppositevsides of 'the .baling chamber for the purpose ofcarrying the'balf` ingwire 9 'through the balingI chamber. at the rear of the bales, to wireclamping devices hereinafter described, disposed at'the opposite sideofthe baling chamber. The

wires 9 are drawn from'two reels 10, which are rotatively mountedrespectively on hori-` zontal studs 11, the inner ends of which'aresecured to the vertlcal side of a baling chamber 1, to which aresecuredthe bearings 7',

as shown in Fig. 2.

12 denotes the opening in the top of the baling chamber through whichthemathe upper end of the shaft 6 is segmentalterialto be fed isinserted in the baling chamber, see Fig. 1. Two horizontal rollers 13,for guidingv the wire 9,'-are rotatively mountedon vertical pivots 14respectively, the upper yand lower ends of which are securedin brackets15, fastened aty therear of the opening 12 to the vertical sidevof thechamber 1, to which are secured the bearings 7, as shown in Figs. 1 and2. The forward end of the plunger 2 is provided with two longitudinalhorizontal slots 16, Lwhich extend transversely through the plungery 2in the same horizontal planes respectively in which are located theslots 8. -Two horizontal rollers 17, are rotatively mounted in thevslots 16 respectively of the plunger 2 and extend laterally respectivelythrough adjacent slots 8. The rollers 17 are peripherally grooved so asto receive therein the. wires 9. 'The shaft 6 is rocked by the followingdescribed mechanism z-Secured to bevel gear wheel 18, which meshes witha bevel gear wheel 19, rigidly secured to one end of a horizontal shaft19, which is rotatively mounted in bearings 20, which are secured uponthe upper side of the baling chamber 1. Secured to the other end of theshaft 19 is a crank arm 21, to which is pivoted the forward end of arearwardly eX- tending. rod- 22, the rear end of which is pivoted to acrank pin 23, secured eccentr# cally and horizontally lto a verticalbevel gearwheel 24 which' is rotatively mounted lon the shaft '5. Thebevel gear `wheel 24L c is located in the recessed outer side of a disk'V30 which isv rigidly secured to. the shaft 5.

In the inner periphery of' the-recessed outer end Aof the-disk 30 isprovided a notch 31 adapted to receive the outer end of the pawl 29;Y`Aflat spring32 is secured at one end toa horizontal p1n'*'33 secured tothe inner fside'of the gear 24, the opposite end of the spring bearingupon t-he pawl 29 so as to force the pawl into the notch 31. The pawl 29 is provided with an arm i 34 which :projects beyond the periphery ofthe disk 30 and is adapted to strike a crank arm 35 provided at theouter end of a horizontal bar 36, which is slidable longitudinally in abearing 37 the inner end of which is secured to the baling chamber 1. Acoil spring 38 encircles the bar 36'and`has its outer end bearingagainstfthe arm 35, and its inner end bearing against the bearing 37.The

spring 38 normally forces the bar 36 to a position in which the arm 35will be disposed inthe path of movement of the arm 34. In such positionthe arm 35 will hold the arm 34 and the pawl 29 will be forced againstthe pressure of the spring 32 from the notch 31, thereby releasing thegear and stopping its rotation. To retract the bar 36, it has securedtransversely in it a horizontal pin 39, which extends through ahorizontal transverse hole 40 provided in the bearing 37. One end of thepin 39 is pivoted toa crank arm 42 of a horizontal rock shaft 43 mountedin bearings 44 secured to the adjacent side of the baling chamber. Therock shaft 43 is provided with a crank arm 45 by which the shaft may beo erated to withdraw the bar 36 to release t e gear pawl 29 fromengagement With the arm 35. When this is done the pawl enters the notchSlof the rotating disk 30 and the shaft 6 is rocked so as to swing theneedles 7 from the position shown in Fig. 1 to the position shown indotted lines in Fig. 6 and in solid lines in Fig. 8, through theintermediacy of the gear 24, rod 22, crank 21, shaft 19', gear 19 andsegmental gear 18. As soon as the rock shaft 43 has been rocked toretract the bar 36, the rock shaft is released, so that the spring 38will force the bar 36 into a position in which the arm 35 will engagethe c- `zontall in 49, secured 'tot the jaws 47,'the `cirf* cular orward end ;5 O,` of 1t-rearwardlyI ex-f ungenirodj, l

A flat spring 69 is secured at its forward endagainst the forward end of the finger 66 by the screw 65. The rear endof the spring 69 bears against the outer side and rear end of the finger66 and -normally holds the finger 66 in the position. shown inv Fig.'23. A rod 70 hasits rear end secured rigidly tol-the forward end of thelplate 64 and normally extends forwardly a and upwardly to a position inwhich it will be depressed by the adjacentneedle 7, so as to swing theplate 64 and the linger 66 to a position in which the projection 68 willengage and hold the wire 9 when the wire 9 Vis released from the roller17 upon the plunand normally holds said rod and finger 66 kThe plunger 2will now in the position shown in Fig. 22. In this position the plunger2 carrying the rollerl 17, can pass toaposition in which the roller 17will be forward of the projection 68 without the roller striking. saidprojection.

After the ends of the wires 9 have been secured, as has been described,between the clamping jaws -47 and 52, as shown in Fig. 29,'the plunger 2is reciprocated and the charges of hay successively fed into the balingchamber 1 through the feed opening 12. When sufficient hay has been fedinto the baling chamber to form a bale the wire 9 will extend across theforward end and along the. two sides of the bale, as shown in dottedlines in Fig. 30, the bale forcing the wire to this position. The crank45 of the rock shaft 43 is then operated to cause the needles 7 to swingthrough the slots 8'of the baling chamber to the position shown indotted. lines in Fig. 6.l As theA plunger 2 moves forward from theposition shown in solid-lines in Fig. 6, theneedles 7 will swing throughthe slots 8 and the slots16-of the plunger and will engage the two wires9 in f their'forked outer ends and-will carry said wires between theinclined ends 48 of the jaws 47 and the levers 51 forward of the jaws52, in which position the wires which have just been'folded across therear end of the bale to the position shown in Fig. 31, will be held butnot clamped by the jaws, the ends of the wires, however, will still beclamped as shown in Fig. 15. At this time the plunger 2 and roller 17will be .in the position shown in Fig. 31, with the roller 17 in advanceof the projection 68 and the needles 7 in the position shown in Fig. 25.

start on' its rearward movement and the wires 9 will be caught and heldby the projections 68, which at this time are raised to the elevatedposi- `disposed at the opposite side tion by reason of the needles 7bearing against the upper sides of the rods 70 respectively. By reasonof the fingers 66 bcing mounted on vertical pivots, said lingers canswing outwardly when struck by the rollers 17 on the rearward movementof said rollers. The wires now being bound around the bale are ready tobe knotted and cut and released from the clamping jaws so that the balemay be moved forward, as shown in Fig. 32, during the formation of thenext succeeding bale.

- I will now describe the mechanism which is preferably employed forperforming the knotting operations z-leferring partielllarly to Figs. 1,3, 7, 8 and 13,-73 denotes two horizontal brackets secured to the sideof the baling chamber 1, which is adjacent to the shaft 26. Rotativelymounted in said brackets 73 respectively, are two horizontal shafts 74,to the rear ends of which are secured respectively two disks 75, havingrespectively secured to their rear sides two bearings 76 in which arerespectively rot-atively mounted two shafts 77, which are rcspectivelyrotatively mounted in two blocks 78, having trunnions 7 9,best shown inFigs. 8 and 13. Each set of trunnions 79 is pivotally mounted in thevertical arms of two right angled, vertical plates 80, which have theirhorizontal arms pivoted on a horizontal pin 81. The upper one of the twopins 81 has its ends mounted respectively in two ears 82 which projectupwardly from the upper side of a horizontal supporting plate 83, theinner end of which is secured to the adjacent side of the baling chamber1, as shown in'Figs. 8 and 13. The lower pin 81 is mounted 1n ears orprojections 84 which extend upwardly from the upper side of a horizontalplate 85, secured to the adjacent side of the baling chamber 1, belowthe plate .83. -As shown in Fig. 4, each of the bearings 76 is'providedwith a central, cylindrical extension 86, which is rotatively mounted inthe disk and is provided with a screw threaded end on which is mounted anut 87, of the plate and which secures the bearing 76 to said disk orplate 75. As shown by dotted lines in Figs. 4 and 13, the portion of theshaft 77, which is embraced by the bearing 76, is reduced in diameter soas to prevent lengthwise movement of the shaft relative to the bearing.The end of each shaft 7 7, adjacent to the baling chamber 1, and at theinner side of the block 7 8, is larger than the portion of the shaftwhich extends through the block 78 so that the shaft cannot, slipoutwardly throughsaid block. To'prevent its slipping inwardly throughsaid block each shaft hassecured .upon it, at the outer side of theblock 78, a bevel gear wheel 88, adapted to engagel a curved rack 89,which is mounted upon the adjacent side of the adjacent disk 7 5A, whenvsaid is riotaffv/ed,`t` in the direction indicated by .thearrowfin Fig.13.

Rigidly secured-respectively'to theshafts 77, at sides opposite from`the bearing's76, j adjacentl to which "are secured the -gear` wheels 88,are two segmental 'bevel gear ,A

wheels 90, which are adapted to respectively mesh withy two curved-racks91, securedrei spectively to adjacent sides ofthe disksl 75."l

The head or forward end 92 of each shaft 77 yis providedat one side.with two-jaws 93" and 194. Pivotally mounted on ftheftransverse pin9.5,secured in lthe jaw 93, is a tongue 96, which has its inner endfnormallyheld against the 'oppositejaw 94' by a .coil 1 spring 97, which yismounted vin "a recess 98, provided lin they inner side of lthfe jaw 93.`

bars 130 extend outwardly over the bars 113 and are provided at theirouter ends respectively with right angled bent portions on which arerespectively mounted two rollcrs136, On the sides of the plat-e 112,adjacent to the bars 130, arev provided two cam 'projections 137, withwhich the rollers 136 are adapted to respectively engage. When the.parts are inthe initial position shown in Fig. 9, and" in solidlines inFig. 10, the rollers 136 lie respectively betweenv the cam projections137 and two pivoted guiding plates 138, which are respectively pivotedto the plates 112 on the sides of the plates provided with the camprojections 137. Two springs 139, which are respectively secured to theplates 112, bear against the pivotcd plates 138 and retain 'said platesin contact with the cam projections 1,37 excepting at such times as therollers 136 are forced upwardly through said cam projections and saidpivoted plates. lVhen the shaft 26 is rotated the plates 112 are oscil-70 lated, first to the position shown in dotted lines in Fig. 10, thento the position shown in solid lines in Fig. 11, then to the positionshown in dotted lines in Fig. 11, and finally to the initial posit-ionshown in solid lines in Fig. 9.

After the operating rock shaft 43 has been rocked, so as to swing theneedles 7 across the baling chamber and the knotter head 92 has beenoperated to engage the strand 80 107, as shown in Fig. 26, the crank 125on the shaft 26, will cause the plates 112 to be oscillated, asdescribed, thereby causing the bars 113 and 130 to be moved first to theposition shown in solid lines in Fig. 10. The plates 138 and 137 willswing the bars 130 so as to close the jaws 132 and 133 from the openinitial position, shown in Fig. 9. Prior to this time the oscillation ofthe plates 112 from the position shown in solid lines in Fig. 10 to theposition shown in dotted lines in said figure, will cause the jaws 132and 133 to be moved while in the open position, downwardly, and towardthe baling chamber 1, to a position in which the strand 106 v95 willpass between the jaws above the tooth 134. When the plate 112 hasreached a. position shown in dotted lines in Fig. 10, the rollers 136will have passed upwardly between t-he cam projections 137 and plates138 and the plates 138 will, by striking against saidrollers, swing thebars to the closed position shownin dotted lines in Fig. 10, therebyclamping the strands 106 between said jaws. At this time the plates 10i112 will begin to swing in the opposite direction, and when they haveswung to the position shown in solid linesA in Fig. 11, the jaws 132 and`133 will have carried the strands 106 upward to a position in which-110 the jaws will clear the strand 107, after which the jaws will bemoved outward from the baling chamber 1, carrying with them the strands106 to the position shown in Fig. 27 and in dotted lines in Fig. 11.Dur- 118 ing this movement the rollers 136 will pass over the outeredges of the cam projections 137 and will thereby be held in positionsin which the jaws 132 and 133 will remain closed. At about this time thelevers 51 will l have been swung to the open position, thereby releasingthe strands 106-from the jaws 47 and 52, andthe knotter heads '92'willhave` been rotated.,` clockwise, to the position shown inaFi'g. 27, inwhich position the 125v strands 106 will have passed between the jaws 93and 94 past the tongues 96 of the knotter heads 92. The knotter heads 92will now begin their reverse movement from the position shown in-Fig. 27to that shown in 13 Fig. 28. When they have yreached the `poy sitionshown inFig. 28, the plates 112 will have been rocked from the positionshowngin dotted lines in Fig. 11 to the initial position shown inFig. 9and in solid lines in Fig.
